National Summary


Limited bright intervals but overall mostly cloudy and misty in places for the rest of today, with outbreaks of generally light rain and drizzle in freshening southeasterly breezes.


Outbreaks of rain and drizzle will give way to persistent, heavy and possibly thundery rain moving in from the Atlantic tonight. The rain will advance slowly across the country overnight, arriving in the east on Thursday morning. Lowest temperatures 8 to 11 degrees. Winds will be moderate to fresh southerly.


Outbreaks of rain will be widespread tomorrow, Thursday, with some heavy and thundery falls, leading to spot flooding in places. The rain will become lighter and patchier from the west towards evening, but will likely persist until around midnight along the east coast. Patches of mist, with hill and coastal fog will contribute to generally poor visibility at times. Top temperatures of 12 to 15 degrees with moderate to fresh southeasterly winds becoming fresh to strong and gusty northwesterly, later in the day.


Active weather systems will bring spells of very wet and very windy weather, with short drier interludes in between. Rainfall will be above normal and spot flooding is likely. On Thursday night the heavy rain and strong northwest winds will clear away to the east. Skies will clear and it will turn cold with lows of 3 to 7 degrees. Some grass frost and patches of mist are likely in places before dawn.Friday: It will be a mostly dry, calm, start to the day. Sunny spells will soon clear remaining mist and grass frost. Wet and windy weather is expected to develop on the southwest coast through the afternoon and evening. Afternoon temperatures ranging 12 to 14 degrees, but feeling cooler in the rain and strengthening southeasterly winds. Current indications show strong gale force winds at sea and strong and gusty winds overland on Friday night. The strong winds will be accompanied by heavy rain, bringing a risk of local flooding. This is due to the track of a deepening Atlantic depression.As the low pressure centre moves over the country the strong gale force winds will continue at sea on Saturday, possibly falling light variable over land. The winds overland are expected to increase through the day from a northwesterly direction and will become strong and gusty, most especially at the coasts. The winds will be accompanied by heavy, possibly thundery showery rain. Another dry and bright interlude for Sunday as winds ease for a time before the next weather system comes in from the west on Sunday night.
